Embodiment 1

[0058] For the underground walkway, the tunneling device of the present invention is used for construction. according to image 3 The schematic cross-section of the outline of the underground pedestrian passage is divided according to the above three standard excavation units. Specifically, type I excavation units and type III excavation units are selected, one type III excavation unit is arranged in the middle, and 10 type I excavation units are arranged The units are arranged on both sides respectively, so as Figure 4 The schematic diagram of the excavation unit modulus of the underground municipal tunnel is shown, and the combination of the two can be obtained as Figure 5 The cross-sectional schematic diagram of the combined roadheader for the underground walkway shown.

Embodiment 2

[0060] Taking the underground municipal tunnel as an example, the tunneling device of the present invention is used for construction. according to Figure 6 The schematic diagram of the outline section of the underground municipal tunnel shown is divided according to the above three standard excavation units. Specifically, type I excavation units, type II excavation units and type III excavation units are selected, and two type III excavation units are arranged in the lower left corner. Arrange 5 type II excavation units on top of 2 type III excavation units, then arrange 10 type I excavation units on top of 5 type II excavation units, finally arrange 8 type I excavation units on the last right side, get as Figure 7 The schematic diagram of the excavation unit modulus of the underground municipal tunnel is shown, and the combination of the two can be obtained as Figure 8 The cross-sectional schematic diagram of the combined roadheader for the underground municipal tunnel s...

Embodiment 3

[0062] For the subway station at the intersection, adopt the driving device of the present invention to carry out construction.

[0063] Process one: if Figure 9 As shown, a subway station is planned to be built at the crossroad 6 position, and the shaft 7 needs to be constructed on both sides of the road earlier.

[0064] Process two: if Figure 10 shown. In the vertical shaft 7, the construction cross channel 8 is dug underground. The cross-sectional schematic diagram of the cross-channel is shown in Figure 11 , specifically select Type I tunneling units, Type II tunneling units, and Type III tunneling units, arrange three rows and two columns of Type III tunneling units in the lower left corner, and arrange five Type II tunneling units corresponding to the two Type III tunneling units on the top row On the top of the excavation unit, arrange 8 type II excavation units on the far right, and finally arrange two type I excavation units on the right side above the type II...

Abstract

The invention provides a modular combined underground engineering tunneling device and a construction method thereof. The modular combined underground engineering tunneling device includes a front device and a rear device. The front device includes at least two tunneling units, and the tunneling units are connected in a combined mode to form a front device that conforms to the contour of an underground project. The tunneling units include tunneling shells, tunneling devices are arranged at the front ends of the tunneling shells, and driving parts for driving the tunneling devices are arrangedin the tunneling shells. The construction method includes the following steps of section division, module determination and initial tunneling. The modular combined underground engineering tunneling device has the advantages of modularizing equipment design and production, reducing the manufacturing cost of equipment; shortening the manufacturing cycle of the equipment and improving the construction efficiency of the entire project; designing of corresponding equipment modules in a targeted mode with wide application range for projects in special fields; and effectively reducing equipment resource investment with good economy.

Description

technical field [0001] The invention relates to underground engineering, in particular to a modularized combined underground engineering excavation device and a construction method thereof. Background technique [0002] With the in-depth advancement of infrastructure construction such as sponge cities, urban three-dimensional transportation, and civil air defense projects in my country, there are diverse needs for underground engineering sections. In the future, there will be a large number of diverse cross-sectional space development needs in construction areas such as comprehensive pipe corridors, underground parking lots, subways, highways, and railways. [0003] The section of conventional shield tunneling equipment such as pipe jacking is fixed, and can only be applied to underground engineering construction with one section. Every time an underground project with a new section is encountered, it takes a lot of time and resources to complete the design and assembly of ...
